Array
(
    [0] => Array
        (
            [country] => España
            [feature code] => PPLA3
            [country code] => ES
            [admin1code] => 51
            [admin2code] => H
            [town_province] => Beas
        )

    [1] => Array
        (
            [country] => España
            [feature code] => ADM3
            [country code] => ES
            [admin1code] => 51
            [admin2code] => H
            [town_province] => Beas
        )

How to remove only one of these! Notice values are always different!

I would like to do this:

  if there are 2 of these:  

 [country code] => ES
            [admin1code] => 51
            [admin2code] => H
            [town_province] => Beas

drop one!

How to remove duplicates from here:

Array
(
    [España] => Array
        (
            [Provincia de Huelva] => Array
                (
                    [0] => Zufre
                    [1] => Zalamea la Real
                    [2] => Vista Alegre
                    [3] => Villarrasa
                    [4] => Villarrasa

define "duplicate" in three dimensions.

but for the first one you maybe use array_reduce() with a hash function that compares the appropriate keys on each iteration. its a question about what to do with the rest, e.g. random drop oder just group by.
